BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention pertains to the art of cooking appliances and, more particularly, to a cooking appliance with a ventilation system, such as an adjustable vent and a corresponding filtration system.

2. Discussion of the Related Art

While cooking, it is often considered beneficial to utilize some type of ventilation system to evacuate the airborne contamination and heated air from the vicinity of the cook top, oven, or other cooking device, either upward through a venting hood or downward into a draft flue. In kitchens, most known venting arrangements take the form of a hood which is fixed above a cooking surface and which can be selectively activated to evacuate the contaminated air.

Downdraft vent arrangements are also widely known in the art wherein a cooking surface will incorporate a vent opening that is positioned upon or extends from the cooktop. During cooking, the heated pots and cooking vessels may radiate heat and effluent-laden air, gases, and fumes. A downdraft ventilation system is used to evacuate this heat and effluent-laden air, gases, and fumes downwards, usually into the cooking appliance housing.

The vertical distance between the cooking surface and a vent hood is typically fixed between 24 and 30 inches. When in an operating position, downdraft vent arrangements known in the art are also limited in this respect. Depending upon the food being cooked and even the particular height of the individual doing the cooking, it may be desired to vary the distance between the cooking surface and the vent inlet. On a cooking surface, it is considered beneficial to arrange a vent closer to the cooking surface in order to increase the removal of contamination. On the other hand, it is often desirable to raise a vent inlet relative to a cooking surface in order to more easily access different portions of the cooking surface or to pull heated air from the vicinity of the tops of cooking vessels.

A cook top using heating for cooking purposes is normally constructed of a metal housing supporting a glass or other cooking surface upon which there is located a number of heating elements.

As noted, many conventional cook tops often have integrated downdraft ventilators. Present designs are rectangular inlets, usually on the surface of the cook top, connected to long rectangular box-shaped ducts extending below the cook top, also known as a plenum.

Downdraft ventilators are generally designed to draw air from the vicinity of the cooktop downwardly at about a ninety-degree angle with the use of a motor assembly having a fan, thereby removing contaminated and heated air from a cook top surface, and exhausting it outside the ventilation assembly or outside the cooking device to return to the room. In such conventional systems, the airflow stream is pulled from the front and sides of the work area to the middle where the ventilator is on the cook top surface. The airflow stream has to then turn 90 degrees downwardly, once inside the plenum chamber.

Present downdraft ventilator designs also present problems when integrated into a cook top. Because of the low profile, spilled food and liquids can enter the grate and removal of the items that are not captured by the filter cannot be removed easily. This is due to the required depth of the plenum and the narrow box size.

Therefore, a need exists for a state-of-the-art indoor or outdoor cooking device with a ventilation and filtration system to reduce heat, fumes, and contaminants in the cook top area to improve the cooking environment, and so forth. Additionally, there exists a need for a cooking device that resists penetration by contaminants and is easy to clean. Further, there is also a need for a proper vent design to efficiently remove undesired heated air from the housing of the cooking device.

SUMMARY OF THE INVENTION

The present invention relates to a mobile or stationary cooking device with a ventilation and filtration system that preferably a) removes heated air, effluents, and contaminants from the cooking environment, b) provides a filtration system that removes the effluents and contaminants from the air, and c) provides easily accessible and easily cleanable or replaceable ventilation and filtration system components. More particularly, this invention relates to an improved cooking device having a manually adjustable vent to optimize the removal of said contaminants and heated air that is easily manually removable for cleaning, and easily reinstalled. In particular, easy access is provided for removal and replacement of filter components and a drip tray for catching grease and other liquids and solids.

The invention preferably includes a cooking device having a housing with one or more heating elements that may be arranged on top of or within the housing. A vent assembly is provided with a manually removable first duct portion having an inlet, and a second duct portion in communication with the removable first duct portion. At least one filter is present for removing effluents from air in communication with a volume of air flowing through the second duct portion. At least one effluent trapping and filtration assembly receives at least one filter. A motor is provided for moving a volume of air into the inlet and through the at least one filter. The housing has an access to remove or insert the one or more filters into the at least one effluent trapping and filtration assembly.

It is thus one aspect of the invention to provide a cooking device with a removable duct element and removable filters for ease of cleaning.

In another aspect of the invention, the cooking device's effluent trapping and filtration assembly includes a filter housing that is slidably accessible from the access opening in the housing. It is thus another aspect of the invention to provide easy access to the filter housing and the replaceable filters within.

In still another aspect of the invention, the effluent trapping and filtration assembly includes a filter housing with at least one filter therein, which is slidably accessible from the access opening in the housing. Thus, the invention preferably provides for at least one filter with easy access through the cooking device housing. The filter may be a grease filter, a particulate filter, or a carbon filter. Thus, the invention may remove effluents and other contaminants, such as grease, smoke, and odor, utilizing a range of filtering types.

In accordance with a further aspect of the invention, the cooking device further includes at least one removable grease and condensate tray in the effluent trapping and filtration assembly that is easily removable from the access opening in the housing.

In yet another aspect of the invention, the effluent trapping and filtration assembly includes an exhaust duct filter housing with at least one filter, which is also easily replaceable from the access opening in the housing. The filter in the exhaust filter housing may be a particulate filter or a carbon filter, where the particulate filter may be a mesh filter, a bag filter, a cartridge filter, or a carbon filter. Thus, the exhaust filter serves to substantially remove the smaller smoke and odor particles from the effluent-laden air.

As described above, the effluent trapping and filtration assembly also has a filter housing that may also house a grease filter and a particulate filter. The grease filter may be a mesh filter, an impingement filter, a baffle filter, a cyclonic filter, or another grease entrapment device. The particulate filter may be a mesh filter, a bag filter, a cartridge filter, or a carbon filter. Thus, it is one aspect of the invention to remove effluents and other contaminants over a range of particle types with a variety of filters for removing grease, particulate matter, smoke, steam, and so forth.

Another aspect of the present invention has a housing further comprising a cart having wheels and a cart handle. Thus, it is yet another aspect of the invention to provide for a mobile cooking device that is easily moved and otherwise repositioned.

In accordance with another aspect of the invention, a cooking device comprises a housing, a cook top having one or more heating elements, and a ventilation and filtration assembly comprising: a first duct portion having an inlet, a manual height adjustment device for the first duct portion, a second duct portion in communication with a first duct portion, and at least one filter for removing effluents from air, in communication with a volume of air flowing through the second duct portion, a motor for moving a volume of air into the inlet and through the at least one filter, and an access opening in the housing to remove or insert the one or more filters into the at least one effluent trapping and filtration assembly. The heating elements may comprise burners on a cook top, a range, an oven, a hibachi, a grill, and the like.

Thus, it is another aspect of the invention to provide for a manually adjustable vent whereby the user may optimize the removal of effluents and gases from the cooking area.

The present invention may also comprise a manual height adjustment device having a handle connected to the top of the vent assembly for manually raising and lowering at least the vent assembly inlet and first duct portion. Thus, allowing the user to easily control the position of the inlet vent.

Furthermore, the present invention may also have a first duct portion that is removable and the handle is configured for removing and replacing at least the first duct portion. In addition, the handle may be removable and reattachable. Thus, it is one aspect of the invention to allow manual removal and replacement of the inlet vent portion with an easily graspable handle that is itself removable for more complete cleaning.

The present invention may also have a fire suppression system. The fire suppression system may be compliant with UL710B or other applicable standards. The system may contain a detector or fire detection apparatus which senses heat, temperature, smoke, resistance, fire, and so forth. The associated sensors may fuse, close a relay, or otherwise send an indication or control signal to enact a fire suppression response. For example, overheated exhaust may be sensed by a fusible link, which activates a damper assembly which closes fire damper louvers substantially eliminating airflow through the ventilation system. In another example, a sensor in communication with the cook top of the cooking device may sense excessive heat or smoke and remove power to the heating elements and the fan in the ventilation and filtration assembly. Fire detection may also cause the release of fire-extinguishing material using, for example, nozzles in the vicinity of the cooking device and internal to the ventilation system.

These aspects of the present invention offer advantages of fire safety, energy efficiency, decreased stress on the blower motor and more rapid cooling of induction hobs (for longer component life), an improved cooking environment with less odor, heat, and contaminants, and a cooking device that is able to be used more efficiently to prepare a wider variety of foods. These and other aspects of the present invention will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings. It should be understood, however, that the following description, while indicating preferred embodiments of the present invention, is given by way of illustration and not of limitation.

1. System Overview

The present invention relates to an indoor or outdoor cooking device having a ventilation and filtration system for removing heated and effluent-laden air and gases from the cooking area. Briefly, this is accomplished by providing a manually adjustable vent connected to a filtration assembly that may include traps and filters for removing grease, particulate matter, effluents, and the like. Also disclosed is a manually removable duct portion with an attached vent cover that can be easily removed with a handle, cleaned, and then replaced. The handle itself may be removable for more thorough cleaning. The inventive cooking device may be a mobile unit, an island unit, or an otherwise fixed location unit.

With the increasing heat and effluent emissions from cook tops and the reduction in overall form, removal and filtration of heated and effluent-laden air from the cooking area has become a much more important element of cooking product design. The performance, reliability, and life expectancy of the cooking device, and the comfort and environment of the cook, are strongly related to proper management of the heated and effluent-laden cook top air. Long life with increased reliable performance of a component may be achieved by effectively controlling the device operating temperature and exposure to contaminants in the effluents and gases. In addition, controlling the exposure of the cook and the cooking device to the effluent-laden air may improve the user's experience. Furthermore, the cook, restaurant staff, and guests will have a more pleasant restaurant experience.

In one embodiment, the cooking device preferably comprises a ventilation and filtration assembly having a filter housing that is slidably accessible from an access opening in the housing wherein the filter housing houses at least one manually removable filter. The filter housing may have a filter that may be a grease filter, a particulate filter, or a carbon filter. The ventilation and filtration assembly also has an exhaust filter housing that may house a carbon filter or particulate filter.

Thus, it is one aspect of the invention to provide a ventilation and filtration assembly that is easily accessed for cleaning, replacement, and so forth.

In another embodiment, the cooking device may provide a ventilation and filtration assembly having an exhaust filter housing with a manually removable exhaust filter therein accessible from the access opening in the housing, which is one selected from a group of a disposable carbon filter and a washable carbon filter. The manually removable filter may be a mesh filter, a carbon filter, or a filter configured to substantially remove particles such as smoke particles and odor particles.

The housing may further include a cart with wheels and a cart handle. Thus, it is yet another aspect of this invention to provide for a mobile cooking device that is easily moved or otherwise repositioned.

In accordance with another aspect of the invention, the cooking includes a housing with one or more heating elements and a ventilation and filtration assembly. The assembly preferably includes a first duct portion having an inlet, a manual height adjustment device for the first duct portion, a second duct portion in communication with a first duct portion, and at least one filter for removing effluents from air, in communication with a volume of air flowing through the second duct portion. A motor is provided for moving a volume of air into the inlet and through the at least one filter. An access opening in the housing allows for removing or inserting one or more filters from the effluent trapping and filtration assembly.

Thus, the inventive, manually-adjustable vent allows the user to remove effluents and gasses from the cooking area.

The present invention may also include a manual height adjustment device having a handle connected to the top of the vent assembly. The handle aids in manually raising and lowering the vent assembly inlet and first duct portion, and allows the user to better control and adjust the position of the inlet vent.

Furthermore, a first duct portion may also be removable and a handle may be configured for removing and replacing at least the first duct portion. In addition, the handle may be removable and reattachable. The inlet vent portion preferably has an easily graspable handle that is itself removable for more complete cleaning.

In yet another embodiment, the cooking device may also have a fire suppression system operably connected to the cooking device. The fire suppression system may have a sensor for detecting a temperature, a resistance, a heat, a smoke, and/or a fire. Thus, this system provides for a safe and fire-suppressive cooking environment.

The preferred inventive method of removing effluents and contaminants from the cooking environment includes steps of:

-   -   a. drawing a volume of air proximate to the cooking device into         a ventilation inlet using a motor;     -   b. directing the air through at least one substantially vertical         duct;     -   c. directing the air over a substantially horizontal surface for         collecting effluents thereon;     -   d. directing the air through at least one filter for filtration         of effluents;     -   e. directing the air through a baffle in communication with the         motor; and     -   f. directing the air through a substantially vertical exhaust         filter.

Thus, the invention provides a method of eliminating effluents and other contaminants from the cooking environment through a series of steps of ventilation and filtration.

2. Detailed Description of Preferred Embodiments

Various embodiments of the present invention are shown in FIGS. 1 through 7 b are described in additional detail below.

FIG. 1 shows one preferred embodiment of the cooking device 10 of the present invention. In this embodiment, the cooking device 10 includes a housing 18, and a cook top surface 12 with heating elements shown as burners 14, 16. The housing 18 and cooking surface 12 are preferably comprised of a metal, glass, stone, plastic, other materials, or a combination thereof.

The device 10 has a cook top vent assembly 20 for removing effluent and hot air from the cooking surface or cooktop 12. The vent assembly 20 may consist of a substantially vertical duct portion 22 and vent inlet 24. A handle 25 may be provided for manually raising and lowering the vent assembly 20. The outer surface of the vent assembly 20 is preferably made from metal, although glass, stone, plastic, other materials, or some combination thereof may be used. Because of the flexibility of the design and the low profile, the outer shape of the vent assembly 20 can be styled to meet nearly any requirements.

Also shown in FIG. 1 are various controls 26 which may include controls for heat or temperature settings for the burners 28, 30, a control for the speed of the ventilation motor 32, and the like. In addition, the cooking device 10 of FIG. 1 may comprise a cart 33 that includes wheels 34 for mobility and a handle 36 for ease of movement. Furthermore, the cooking device 10 may also have an access panel 38 for access to internal removable components further explained below. The access panel 38 may have a handle 40, and provide for ventilation with openings 42.

FIG. 2 shows the interior of the embodiment of FIG. 1 with the cooking device housing 18 and cook top 12 removed to show the vent assembly 20 and effluent trapping and filtration assembly 54, which may be an integrated assembly 50. As mentioned, the vent assembly 20 may consist of a substantially vertical first duct portion 22 and vent inlet 24 and may have a handle 25. In addition, there is a second duct portion 52 (as shown by its external housing surface), which may slidably receive the first duct portion 22. The first duct portion 22 may also be removable from the second duct portion 52 using handle 25. The integrated assembly 50 also has an effluent trapping and filtration assembly 54 which contains filters 51 and effluent traps 53, as will be described below. The filters 66, 68 and grease trap 64 (as shown below in FIGS. 3 a-c) are accessed through access panel 38 (as shown in FIG. 1) which may have an additional door or drawer 56 having a handle 58 for accessing the filters and traps within. The effluent-laden air is moved through the integrated assembly 50 by motor 60. The air moves through blower assembly 61 and exits from the exhaust filter housing 62.

Referring now to FIGS. 3 a-3 c, the operation of the integrated assembly's 50 vent assembly 20 and effluent trapping and filtration assembly 54 is illustrated. Starting with FIG. 3 a, a cross-sectional side view taken along axis 3 a-3 a in FIG. 1 is shown. Vent assembly 22 is shown extended with air designated by arrow A₁ entering the vent inlet 24. The air flow A₂ turns downward and travels vertically downward through the first and second duct portions 22, 52 and turns at about a 90-degree angle to flow substantially horizontally into the lower portion of the filtration assembly 54 as shown by airflow arrow A₃. The airflow may release liquid or solid effluent onto an effluent receptacle shown as drip tray 64. The airflow then turns at about a 90-degree angle to flow upward into the filters 66, 68. The filtration assembly 54 may contain one or more filters such as filter elements 66, 68. The effluent-laden air moves through the filters which remove some of the effluents. The air continues upward, shown by air flow arrows A₄, and into the blower assembly 61 having an air-moving element such as blades 63 being moved by motor 60. FIG. 3 b shows another cross-sectional side view of the integrated assembly 50 taken along axis 3 b-3 b in FIG. 1. This cross-section shows the major airflow path A₁ into the vent 22 and A₅ through the vent 52 and upward through the filter housing 54. FIG. 3 c shows yet another cross-section front view of the assembly 50 taken along axis 3 b-3 b in FIG. 1. Airflow A₁ enters the vent 22 through vent inlet openings 24. The airflow may move vertically downward (not shown) and then upward as shown by airflow arrows A₆ through the filter elements 66, 68 of the filtration assembly 54. The airflow A₇ proceeds through the blower assembly 61 impelled by motor 60 and makes a turn of about 90 degrees to form airflow A₈ which exits thorough the exhaust filter housing 62 as exhaust air flow A₉.

Two types of ventilators may be used with the present invention, ducted and non-ducted. In a non-ducted-type ventilator, there may be outlets, but no duct that is used for venting air to the outside. See, e.g., FIG. 1. This embodiment has exhaust outlet vents 42 that are not in communication with a duct. Alternatively, the outlet vents or openings 42 may be at the top, back, or bottom of the housing 18 for directing exhausted air upward, sideways, or downward. In a ducted-type ventilator, there is a duct that is used for venting air to the outside (not shown) in communication with one or more outlet vents. Similarly, this duct unit can be vented at the top, side, back, front, and/or directed downward to the floor in a room.

Turning now to FIGS. 4 a and 4 b, the operation of the telescoping vent assembly 20 is described. The cooking device 10 of the present invention is shown with the first vent portion 22 flush with the cooking surface 12 in FIG. 4 a. In this embodiment, the vent may be operable for moving air while vent assembly 20 is in the lowered position. In FIG. 4 b, however, the telescoping vent assembly 20 is shown in the extended and operable position, having been manually raised by the user.

Referring now to FIG. 5, the operation of the removable and replaceable components of the cooking device 10 is detailed. The cooking device 10 is shown with an effluent trapping and filtration assembly 54. Here, the effluent trapping and filtration assembly 54 is shown as an extended drawer 70 with an upper filter element 68 that is visible. The filter element 68 is removed revealing a lower filter element 66. The lower filter element 66 is removed from the drawer 70 to reveal a portion of the effluent-receiving surface, here shown as drip tray 64. Once filter assembly drawer 70 is removed, the drip tray 64 can be seen partially extended (65). Another removable component is shown, i.e., the exhaust filter 72 that is being inserted (74) into the drawer 70.

Turning now to FIGS. 6 a and 6 b, the removal and replacement operations of the handle 25 are shown. A close-up of the top 27 of the first vent portion 22 shows handle 25. Handle 25 may be removable by allowing it to rest against the top of the vent 27 as shown in FIG. 6 a. From this position, the handle 25 may be removed by lifting a lower portion of the handle 31 along path M, which lifts the handle 25 from opening 29. Otherwise, the handle 25 may be in a raised position as shown in FIG. 6 b. In this position, a lower portion of the handle 31 is positioned so that it cannot be removed from opening 29.

Referring now to FIGS. 7 a and 7 b, the retraction and extension operations of the handle 25 are described. The handle 25 may be raised through opening 29 so that it is fully extended from the vent 22, as shown in FIG. 7 a. Alternatively, the handle 25 may be retracted so that it is flush or below top surface 27.

Referring again to FIG. 1, one embodiment of the cooking device 10 has a fire-suppression system sensor 100 operably connected to, for example, the exhaust filter housing 62 for sensing and suppressing fires for added safety. A temperature-sensing and fire-suppression system that is electronic or mechanical with fusible links may be employed in such a system. The temperature-sensing system may be operably connected to the cooking device or cook top for detecting at least one of temperature, resistance, heat, fire, or smoke. Such sensors may have at least one of an electronic, an electromechanical, and mechanical component.

There are virtually innumerable uses for the present invention, all of which need not be detailed here. Of course, this and all of the other disclosed embodiments can be practiced without undue experimentation.
